SPECIFICATION forming part of Letters Patent No. 539,999, dated May 28,1895. Application filed February 10, I894. $erial No. 499,772 (Nomodel.)

plemental bed having a vertical adjustment and there is employed in theconstruction represented in the drawings a plurality of tool holders allof which are mounted upon and reciprocate with the carriage but arecapable of a movement at right angles to the travel of the carriage,while the tool chucks are capable of an adjustment independent of suchlat-- eral movement of the tool holders. The distinguishing features arethe vertically adj ustable bed, the reciprocating carriage, thelaterally adjustable holders and the separately adjustable tool chucks.There is also provided suitable mechanisms for effecting thereciprocation of the carriage, the lateral movement of the bed, thevertical adjustment of the supplemental frame, and the lateral and otheradjustments of the tool chucks and tools, together with a stop andreversing mechanism for effecting a change in the direction of movementof the carriage and for feeding the material by the lateral adjustmentof the sliding bed. These last named mechanisms operate automatically,while the adjustments spoken of are manual.

In the accompanying drawings, Figure 1 is a side elevation. Fig.2 is aplan. Fig. 3 is a vertical transverse section. Figs. 4 and 5 show amodified construction of the bed in plan and elevation, respectively;and Fig. 6 isa detail view, partly in section, of the toolholdingmechanisms.

In the drawings, 10 represents the vertical standards, which constitutethe end portions of a supporting frame and which are connected at theirlower, ends to a suitable foundation 11, while their upper ends areconnected by the top plate 12. On the inner faces of the end standardare provided the guides 13, and slidably mounted on these guides is thesupplemental frame 14, which is provided at each end with a nut 15.Threaded shafts 15 engage these nuts, said shafts being placed in avertical position and carrying on their upper ends, above the top plate12, the bevel gears 17. An adjusting shaft 18, journaled in bearings onthe top plate, has bevel pinions 19 enmeshed with the bevel gears 17 anda crank handle which affords means for rotating the adjusting shaft andthrough the bevel pinions and bevel gears above mentioned effects thevertical adjustment of the supplemental frame.

21 represents a screw shaft extending lon-' gitudinally of thesupplemental frame, its ends having hearings in the-end pieces of theframe, and the forward end of said shaft being extended through anopening in the front' standard and provided with a bevel gear 22enmeshed with a gear 23. I The bevel gear 23 is carried upon a verticalshaft 24, the latter being rotatable and having a longitudinal slot orkey seat24 in order to permit the gear 23 to slide up and down thereon.In order to secure the gears 22 and 23 in position to enmesh at allpositions of the sliding or supplemental frame, I employ an anglebracket 25, which is fitted to slide in suitable ways 26 on the upperface of the front standard, and which has a bearing at theextremity ofeach ofits members, one of the bearings receiving the extended end ofthe threaded shaft 21, the other bearing receiving the vertical shaft24, and the bevel gear 23 being splined on the shaft 24 above thehorizontal member of the angle bracket. The threaded shaft 21 engagesand reciprocates the carriage which carries the tool in a mannerpresently to be described. The vertical shaft 24 roo '. ways 47. The bed46 has a nut 46 and a plemental frame and transversely thereto, thecentral portion of said block resting in the operative position againstthe lower side of said frame and the block being provided with thevertical cheek pieces 35 on the up- 14. The carriage has a nut 34through which shaft 21 is threaded. The central block or body of thecarriage projects at substantially equal distances on each side of thesupplemental frame and is constructed to provide suitable ways 37 onwhich slide the head blocks 38. Said head blocks have nuts 39 with whichare engaged thread-ed adjusting shafts 40, by means of which the blocksmay be moved along the ways at right angles to Each the direction oftravel of the carriage. of the head blocks carries a guide 41, and uponthese guides are slidably mounted the blocks 42 on which are pivoted thetool holders 43. The blocks 42 have nuts 42 and threaded shafts 42working in the guides 41 and engaging said nuts afford means for.adust-mg said blocks carrying the tool holders vertically.

The guides 41 may be formed integrally: with the laterally slidingblocks 38, but in the construction shown they are held thereto by bolts41 passing through curved slots 41 in the guide, so as to provide foraset ad j nstmentof said guides.

machine are capable of being set obliquely; and this may be accomplishedby pivoting the tool holders upon a slotted plate 44, the latter beingclamped to the blocks 42 by bolts 45 projecting through the said slotsand provided with tightening nuts. In this case the tool holder may haveits position angularly changed without changing the position of theguide. This position is shown at the right in Fig.3, while a secondaryposition of the guide, block, tool and tool holder is shown by dottedlines at the left of said Fig. 3. The slots will be of such length as toenable the tool to be adjusted through an arc of ninety degreesoutwardly from a horizontal plane and also inwardly sufficiently to cuton a bevel surface. This range of movement adapts the cutters soconstructed to varying positions in which it may be convenient toarrange the work, and adapts the machine as a Whole to operate with someof its cutters upon material arranged with the surface to be planed in ahorizontal position, While others of the cutters may be worked upon thesurface of material arranged in a vertical position at the side of themachine.

In Figs. 1, 2 and 3 I have shown a bed 46 which is arranged to slide onthe stationary threaded shaft 48 engages said nut and is provided at oneend with an operating handle or crank 49 and also with a ratchet 50 anda bracket standard 51 "carrying a spring conon the front standard of theframe.

1 tomatic feed is shown. As shown the tool holders on eachside of the rtrolled pawl 52. This bracketstandard is connected with a belt shiftingmechanism which is operated automatically by the traveling carriage andwhich will now be described. The carriage has a perforated stud 53through which a sliding rod 54 passes, said sliding rod having alengthwise reciprocation through suitable keepers 55 mounted on thesupplemental frame. Said sliding rod carries also the adjustable limitblocks 56 between which the stud on the carriage moves, and at itsforward end this slide rod is connected with one member of a pivotedbell crank lever 57 bya link 59, the other member of the bell crankbeing adjustably connected by a rod 60 with a second bell crank 6.1mounted on a stud 58 The forward member of this bell crank is connectedby a .rod 62 with a shifting bar 63, the latter having the shippingfingers 64 which straddle the belt. Obviously, when the carriage in itstravel reaches one of the limit lugs on the shifting rod, the latterwill be reciprocated endwise and, through the described connection,shift the belts from one set of pulleys to the other, thereby reversingthe direction of movement of the train of gears by which the carriage isreciprocated. I also prefer to effect the lateral movement of the bedand the consequent feedof the material carried thereby automatically,and in Figs. 1 and 2 of the drawings the mechanism for effecting thisan- Said mechanism comprises a rock shaft '65, which is journaled inhearings on the bed guides and which is connected by means of the arm 66and link 67 with the bell crank 61. As the adjustment verticallyof thesupplemental frame on which the carriage is mounted will efiect thisshifting mechanism, I prefer to connect the feeding mechanism of the bedadjustably with the bell crank, and to this end there is secured on saidbell crank a slotted arm 68 and the forward end of the rod 67 has a pintraversing the slot of said arm and is adapted to be locked therein bythe set nut 69. The rock shaft has a second arm 70, which is connectedwith the bracket standard 51 by the rod 71.

In Figs. 4 and 5 I have shown a modified construction of the bed, whichmodification consists in mounting the bed upon travelers 72, which areshown joined in pairs by the axles 73, the latter being adapted to turnin' bearings on the bed. The travelers troll upon rails 74, and the bedis provided with the racks 75 in which are enmeshed the gears 76 on thewhich they are in contact.

ferred construction, which is shown in Figs. 1 to 3 inclusive, will nowbe described. The material being operated upon is suitably clamped uponthe laterally movable bed, the carriage is run back and the toolsadjusted in position to engage the work. The belts being driven, thecarriage is advanced, the several tools operatingupon the surfaces withWhen the carriage in its travel reaches the forward limit lug of theshifting mechanism, the belts are shifted and the return movement of thecarriage begins. In the forward travel the cutters or their tools on thefront side of the carriage are in operation while those on the rear ofthe carriage simply ride over the'work, their hinged connection with thecarriage permitting them to thus operate. On the backward movement ofthe carriage the cutters on the rear side of the carriage will out whilethose on the front side are out of action. At the end of the movement ofthe carriage in either direction and at the time of the reversal of itsmovement the bed is automatically moved laterally, thus feeding thematerial so as to bring a new portion of the surface thereof under theaction of the tools for the next line of cut.

If the construction shown in Figs. 4: and 5 be employed, the feedingwill be done manually at the end of each movement of the carriage.

It will be observed that the arrangement of the carriage and thecutter-heads is such justments, which greatly increases the capacity ofthe machine, as the cutting is eifected while the carriage is travelingin either direction. Moreover, by means of the independent verticaladjustment, the work may be cut in two difierent horizontal planes, orin planes at right-angles, or beveled and surfaced at one operation.

I claim- In aplaning machine, the combination with the main framethereof, of a vertically adjustable frame located between ways in saidmain frame, a tool carriage adapted to slide upon said frame, and havingits ends project ing at opposite sides of the frame, and vertically andpivotally adjustable tool-holders mounted upon the projecting ends,whereby the work may be cut in various angular positions, substantiallyas specified.
